Modern Formula 1 is all about aerodynamics. And no track is more aero-dependent than Barcelona's Circuit de Catalunya. No surprise that only three times in 20 years has the team winning there failed to clinch the Constructors' Championship.
That's bad news for Red Bull's rivals. Barcelona is an Adrian Newey playground. Last year, at the fast Campsa corner, Mark Webber and Sebastian Vettel were able to hurtle through at full throttle in sixth gear in qualifying - a gear higher than the team's rivals. Unless Ferrari or McLaren have made a giant leap forward, which is almost inconceivable, only a disaster for the team will prevent a fourth Red Bull win in five races.
The question is, which driver? Vettel is clearly the favourite having lead over 80 per cent of this year's racing laps and taken all four pole positions. With a 38-point lead over Lewis Hamilton, it's way too early to declare him champion-elect, but history tells us that a runaway leader early in the season is very often still there come the end.
In Barcelona, it's surely Webber's chance to stake a claim for the title. He won here last year, leading every single lap from pole position, backing it up with another triumph a week later in Monaco.
